Hispanics and Jews don’t really exist either, at least as races, yet they’re often treated as such.
Referring to your race as Hispanic, makes about as much sense as referring to it as Canadian, American or Australian.
It’s more a nationality, or a supranationality than a race.
Italy was built by Italians and to this day is predominantly Italian, culturally, ethnically and (sub)racially, whereas Hispanic nations were built by Spanish settlers, immigrants from various parts of Europe, Native Americans and African slaves, and so a Hispanic person can be descended from any or all of the aforementioned people, even from Asians who came later, culturally, ethnically and/or racially.
Theoretically Jews are more a clan than a race, in that they’re all supposedly descended from their patriarch ‘Abram’, as well as a culture, ethnicity and religion.
Racially most of them are either of European, West Asian or North African stock, or some combination thereof, but some are predominantly Subsaharan African, like Ethiopian Jews.
Many Jews don’t even have the same culture, speak the same language, or practice the same religion.
A Jew can be a German, Pole, Spaniard or Moroccan, they can speak Arabic, English, Hebrew or Yiddish, they can be an atheist, Buddhist, Christian or Jew.
So they barely exist as a people, again they’re all supposedly descended from their patriarch Abram, 3 or 4 millennia ago, but who fucking knows, there’s no way to prove that.
Really there is no such thing as Jews, and so nothing to rally around, or protect.
There’s no one thing they all have in common, and so we need better categories to describe these, entities.
